Title: Soldering tool for making contacts on semiconductor chips - using soldering bit shaped to reduce soldering time
Inventor: DEHAINE GERARD
IPC: B23K3/047
Filed: 1975-04-01
Abstract: Soldering tool, functioning by the Joule effect uses two pillars or arms connected to the two poles of a current generator and joined at one of their ends by a soldering tip or bit. The novelty is that the bit consists of a foot linked to the arms by two side flanges, each flange possessing the same thickness as the foot, but the width of the flanges tapers continuously from the end of the arms to the foot. The two side flanges and the foot pref. consist of a single piece of metal selected from Mo, Ta, Ti, W or their alloys. Used esp. for soldering conductors onto integrated circuit chips. The soldering or welding operation can take =80 milliseconds, thus reducing mfg. costs.

Title: Typewriter carriage drive - cables winding onto spiral-grooved reversible motor pulley and with tensioning equipment
Inventor: KAMIKOJIMA HIROO
IPC: B41J19/20
Filed: 1975-06-09
Abstract: The drive incorporates a reversible motor (1) with a spiral-grooved pulley (3) and a pair of cables (4, 5) each anchored to the pulley at one end and to the carriage (6) at the other. A pair of pulleys are mounted on the carriage, and there are a further two sets of pulleys (8-11) at the opposite ends of the carriage track. Two more return pulleys (12, 13) are near the track ends. The cables are wound onto the motor pulley so that as this turns one is unwound and the other wound up. The ropes are kept taut, and the cables are reeved from the motor pulley round the track end pulleys, those on the carriage, the return pulleys and to their anchorage points on the carriage. The track end pulleys can be so mounted that the cables run on and off the motor pulley at an angle virtually the same as the helix angle of the spiral grooves.

Title: Ballast system for dirigible airship - has compressed air pumped into or discharged from reservoirs
IPC: B64B1/70
Filed: 1975-07-22
Abstract: The dirigible airship has compressed air reservoirs (10) each side of its centre of gravity. An air compressor (12) supplies air from the atmosphere through the non-return valve (14) to the reservoir (10). A valve (16) controls the discharge of air to the atmosphere and the safety valve (18) prevents excess pressure. The altitude of the airship is increased by discharging air. The altitude is reduced by pumping more air into the reservoir (10). The angle of inclination of the aircraft can be adjusted by filling the reservoir at only one end of the airship. High pressure reservoirs can be near the centre and low pressure reservoirs remote from the centre of gravity.

Title: Broadband magnetic tape recording system - has recording current gated through to transducers only for appropriate length of track to reduce crosstalk
IPC: H04N5/782
Filed: 1975-09-26
Abstract: The broadband magnetic tape recording system has one or more magnetic transducers which are arranged on the circumference of a rotating head and which move over the magnetic tape to form a series of tracks inclined to the direction of motion of the tape. The recording current is gated through to the magnetic transducers only for the appropriate length of recording track section. The advantage lies in reducing crosstalk between the video and audio signals by separating them completely. The system also allows the tape to handle larger information densities and therefore more information per unit length.

Patent FR-2318462-A1 (FR)
Inventor: ROSENBAUM WALTER S
IPC: G06V30/262
Filed: 1976-06-09
Abstract: A digital reference matrix apparatus is disclosed for verifying input alpha words from a keyboard, character recognition machine, or voice analyzer as valid linguistic expressions. The organization of the digital reference matrix is based upon the character transfer function of the input apparatus. The digital reference matrix contains a vector representation for each dictionary word in the form of a calculated vector magnitude and unique vector angle. The set of magnitudes and angles is stored in the digital reference matrix using a form of run length coding by storing a single magnitude pointer followed by the chain of unique angles for words having the same magnitude. The vector magnitude so calculated constitutes the address data for accessing the digital reference matrix. When an input word is received for verification, the word's magnitude and angle attributes are calculated and the digital reference matrix is accessed at the magnitude of the input word and the corresponding angles are searched for a match. An output signal is generated indicating whether or not the input word is valid. The organization of the digital reference matrix minimizes the size of the array needed for accurate word verification representation through the use of the combination of digital angle representation and run length compaction of the magnitude/angle verification syntax.

Title: Phenothiazine purification - by high vacuum distillation of its solution in a high boiling point solvent
Inventor: ZUPANCIC BORIS
IPC: C07D279/20
Filed: 1977-02-09
Abstract: Phenothiazine (I) is purified by a process in which it is dissolved in an inert, high-boiling solvent and distilled under reduced pressure. Cooling the distillate allows the phenothiazine to crystallise out and the mixture is filtered. Typical high boiling solvents include hydrocarbons, phthalic esters, and esters of mono- and polyalcohols with aliphatic mono or dicarboxylic acids. In an example, 80g technical phenothiazine was dissolved in 100 ml dibutyl phthalate and the mixt. distilled under high vacuum, at a head of 185-195 degrees C. The distillate was cooled and filtered to give 58.1 g phenothiazine, m.pt. 186 degrees C. (I) is an intermediate for pharmaceuticals. The process is simpler to carry out than known purification methods.
Patent FR-2386411-A1 (FR)
Title: Injection moulding thick thermoplastic sections in thin walled stages - using ribbed cavity inserts and successive over-moulding
IPC: B29C45/16
Filed: 1977-04-04
Abstract: Large components are injection moulded in stages using two or more moulds successively with inserts which subdivide the mould form into segments comprised of complementary thin-walled sub-components. Moulding of a gear leverl knob in two or three stages is illustrated. Used for moulding thermoplastic forms into shapes which would distort or rupture (internally) due to differential cooling and shrinkage if moulded as a thick section. The thin moulding sections may be cooled relatively efficiently, e.g. due to conduction to adjacent tool faces, so that the cumulative moulding cycle is shorter than that required for a thick one-piece moulding to become stable.
Patent FR-2390593-A1 (FR)
Title: Demarreur a inertie pour moteur a explosion
IPC: F02N5/04
Filed: 1977-05-12
Abstract: Dans de nombreux cas, après une tentative de démarrage, un flux rémanent subsiste entre l'armature 28 et le bobinage inducteur 26, de sorte que le volant d'inertie 16 reste collé contre l'armature 28 et empêche le retour, dans sa position normale, de l'ensemble moteur. Si le moteur à explosion démarre normalement, les vibrations provoquées par celui-ci suffiront à provoquer le décollement de l'embrayage Par contre, si le moteur à explosion ne démarre pas, c'est l'alimentation de l'induit 18 au début de l'opération suivante de lancement qui provoquera la saturation magnétique des sections du circuit magnétique commun à l'induit 18 et à l'inducteur 26. Cette saturation magnétique provoque l'annulation du flux rémanent de l'embrayage et supprime l'attraction résiduelle qui le maintenait collé.

Title: Regulating current to the electrodes in a metallurgical furnace - by measuring the derivative of surface wall temp. relative to time and lowering voltage when this exceeds a critical value
IPC: G05F1/66
Filed: 1977-07-19
Abstract: Regulation of the supply of current to electrodes for a metallurgical furnace for the melting of metals involves measuring continuously the deriv. of the surface temp. of the walls with time and lowering the supply voltage to the electrodes when the deriv. exceeds a predetermined level. During the first part of melting corresponding to the consumption of half of the energy necessary to melt the materials in the furnace, the level is a first value and during the second half of melting, the level is a second value lower than the first value. The invention reduces installation costs and enables a cheaper and more simple form of installation to be used as well as enabling wear on the furnace walls to be reduced.
